NTSB, FBI meet Tuesday to discuss TWA crash

WASHINGTON (CNN) -- With scant evidence about the explosion
of TWA Flight 800, investigators will meet Tuesday to
determine their next step, National Transportation
Safety Board Vice Chairman Robert Francis told CNN.

Francis said that no source of ignition has been found among
the debris recovered since the July 17th crash that killed
all 230 people on board the New York-to-Paris flight.

Investigators are certain that the center fuel tank exploded,
but have no indication why that happened, he said.

"There is no indication that any of the fuel probes had
anything extraordinary about them or wrong with them,"
Francis said. "We're looking for the ignition source and
there's nothing there that's telling us where it is."
